DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 309,752, dated December 23, 1884.

Application filed May 2, 1884.

To all whom, it may concern.-

Be it known that I, lVIATTHEW VAN WORM- ER, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Dumping-Cars; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My present improvements relate, mainly, t the construction of the car-bed and of the truck-frame; tothe rocker and its adjacent parts; to the locating of a platform, from which the operator works the dumping mechanism upon the truck, instead of on the car-body; t0 the dumping mechanism; to the devices and their arrangement for automatically latching and unlatching the side doors of the car-body, and to other particulars hereinafter stated, and they are more particularly applicable to fourwheeled cars.

In the drawings, Figure 1 is a top view of a portion of the truck-frame; Fig. 2, atop view of a portion of the frame of the car-bed; Fig. 3, a partial cross-section showing the position of the rocker on the truck; Fig. 8*, the plates of the rocker-bed; Fig. 4, a view of one of the side supports detached; Fig. 5, areduced side view of the car-body andof the truck; Fig. 6, an end view of the car, showing the devices for dumping, and also showing their relation to the truck-frame; Fig. 7, a bottom View, and Figi' 8 a top view, of one of the rockers; Fig. 9, a detail; Fig. 10, a side view of one of the outside sills of the truck-frame, and Fig. 11 a central longitudinal section through the drafttimber of the truck.

A indicates the car-body, and B the truck. The central draft-timber, C, extends thewhole length of the truck-frame, and at one end projects beyond it far enough to support ablock, D, for supporting a platform, E, on which the operator may stand to dump the car, thus avoiding the annoyance and danger incident to standing on the platform of the car itself. Upon this block D is secured the platform E, on which the operator can stand on a level or (No model.)

non-tilting floor, and can eXert his skill or strength to full advantage. The drafttimber O has cross grooves or recesses l therein to receive the rockers, the upright parts of suchrecesses serving also to prevent thetruck getting away from the rocker, or from being j erked out from under the car-bed when the car is running, for the rocker at its lowermost part rests on its bed between these upright parts or walls. The cross-beams G, on which the rockers act, are short and do not extend from one to the other of the outside sills, H I, but extend only from the stringers J K. They receive the draft-timber in a mortise or recess made at their center on their upper sides, and thus brace the draft-beams laterally, as well as serveto support it, and this mortise also serves to bring the upper surface of these cross-beams about flush with the bottom of the recess 1, to forma level horizontal bed for the rocker, and this bed is faced with metal strips L, as shown. These short beams G avoid the need of using the end bolsters or beams, 2, of the car to sustain the rocker, and the load is supported by the longer cross beams or bolsters 2 2, and by the cross-beams N N, which extend all across the car underneath theoutside sills, the stringers, and draft-beam. The car-bed has, in addition to its outside sills, O, and its centrallylocated stringers l? P 1? P, other and extra stringers, Q Q, placed near the outside sills,

serving the duties of not only aiding to support the floor, but also affording a means for fastening or supp orting the levers R of the latches R,

and also for suspending from them the side supports, S, at each side of the car. These stringers Q, by reason of their location, afford ample space between them and the stringers P to permit the dumping without their interfering with or obstructing the proper movements. When the car is dumped, the inner arms or ends of the latch-levers R are brought into contact with the outside sills of the truck and raised, thus withdrawing the latches from the doors. The rocker T, it will be seen, is a short one, and works or rocks in the space between the stringers J K of the truck-frame. It is operated for the purpose of dumping the car by the following-described devices: Levers U one at each side of the car-are each pivoted, as shown at o, to the truck-bolster, and at their ICC upper ends are fastened to the short chain 10, which is hooked to a hook, w, on the outside sill, and may readily be unhooked therefrom, and from the same hook m the chain extends upward inside of the outside ear-sill, and also inside of the end sill, and its upper end is hooked to the upper part of the end post of the car-body, as shown at y. The windingwheel 6, operated by a crank and gear, 7, has a drum or cylinder at its center, or a shaft, on which the chain 8 is coiled several times, and the two ends of this chain are secured severally to the lower ends of the levers U, the chain also passing over guide-pulleys 9 9. \Vhen the chain is hooked up, as described, on these hooks, it is evident that even if the side supports, S, should become disengaged from their horns 10, yet the car could not be dumped, either accidentally or by turning the wheel 6, because the chain and hook at either side of the car would prevent that side from being raised, and consequently would prevent the opposite side from being lowered; but upon unhooking the chain at either side the car is then free to be lowered at its other side.

The chain may be of twisted wire or wire rope and made of twisted links, so as to readily wind and unwind on its shaft.

To relieve the side supports, S, (which are so hung or pivoted as to swing outward toward the sides of the car, instead of swinging in a direction lengthwise of the car,) I connect to a cross-bar, 11, of each of such supports a chain, 12, which, passing over appropriate guide-put 1eys,13 14, connects along rod, 15, which is pivoted to a hand-lever, 16, on the end platform of the car-body. These side supports not only hang, as stated, so as to be swung out toward the side ofthe car, but, as shown in Fig. 5,when the car-body is level, they hang at aslight inclination, so that their own gravity tends to keep them on their appropriate hooks, and by reason of their swinging outward there results this advantage, that when the support on one side of the car is released preparatory to dumping, then the tipping down of the car on the opposite side will automatically release the other support or supports on that side. The position of the stringer Q relatively to the horn 1O permits these side supports,when hung on the outer sides of such stringers, to assume the slightly-inclined position above named.

The car-frameis purposely made longer than the truck-frame, so that the end sill of the truck shall offer no obstruction when dumping to the fullest movement of the end sill of the car-bed. The ear-bed sill can thus move downward below the ends and corners of the truck-frame. The doors are hung at their tops on the outside of the door-posts by means of a set of eyebolts fastened into the end posts of the car-body and of the doors, as shown at 17, Fig. 5, and a bolt, 18, is passed through these eyes and secured bya nut, 19. The doors thus tend to hang open when not held closed by the latches.

I claim 1. I11 combination with the truck-frame and its end bolsters, 2, extending to the outside sills, H I, the short level cross-beam G, extending only from one to the other of theinside sills, J K, and the draft-timber having the transverse recess to receive the rocker and keep it in position, the cross-beam G serving as the rockenbed, all substantially as and for the purposes described.

2. In combination with the extra stringers Q or Q, located near the outside sills, O, the latches R and the side supports, S, applied to such stringers, all substantially as and for the purposes set forth.

3. The described devices for dumping the car, consisting of the combination, with the winding wheel 6 outside the end of the car, of the chain or wire rope 8, coiled around the shaft of this wheel, guide-pulleys 9 9, levers U, pivoted on the truck-bolster, chain w, and hooks pa 3 on the car, the combination operating substantially as and for the purposes set forth.

4. In combination with the inside sills, Q Q, of the car-bed, and with the horns 10 on the outside sills of the truck-frame, the side supports, S S, hung, as shown, to swing toward the sides of the car, the chain 12, guides 13 and 14, rod 15, and hand-lever 16, all substantially as set forth.

5. In combination with the central drafttimber extending beyond the end sills of both the truck and the car, the block 'D and the fixed platform E, all as and for the purposes described.
